Is periodite a rock or a mineral?
Peridotite is a type of rock that is composed mostly of the mineral olivine, along with other minerals such as pyroxene and spinel. It is commonly found in the Earth's mantle and is associated with the formation of rocks like basalt and gabbro through the process of partial melting.
What is the most massive form of igneous intrusion is?
A batholith is the most massive form of igneous intrusion. It is a large body of intrusive igneous rock that has formed deep beneath the Earth's surface and covers an area of at least 100 square kilometers. Batholiths are often composed of granitic rock and are associated with mountain-building processes.
What is the chemical composition of a basalt?
The mineralogy of basalt is characterized by a preponderance of calcic plagioclase feldspar and pyroxene. Olivine can also be a significant constituent.

What type of rock is an igneous rock?
Igneous rocks are usually classified first by their color index. The color index is separated into four categories. Felsic rocks are the lightest and are composed of mostly quartz and potassium feldspar. Intermediate rocks are the second lightest and are made up of mostly plagioclase feldspar, pyroxene, amphibole, and biotite. Mafic rocks are made up of plagioclase feldspar, pyroxene, and amphibole. Ultramafic is made up of mostly olivine, with pyroxene and amphibole.
Which igneous rock out of granite basalt andesite and peridotite has the lowest silica SiO2 content?
Peridotite, a type of ultramafic rock composed largely of the mineral olivine, has the least silica.

Are dark colored igneous rocks low in silicate minerals?
They are not low in silicate minerals. They are still primarily composed of them. However, the amount of silica in them is lower than in the lighter-colored rocks. The lightest igneous rocks (felsic) are at least 70% silica while the dark ones (mafic) are between 45% and 52% silica. Silica content below 45% is deemed ultramafic.
